POST.

Specification of Letters Patent.

Patented Oct. 4, 1921.

Application filed November 15, 1920. Serial No. 424,072.

have a member partially embedded in the earth.

An object of the invention is to make a post of two different materials, wood for the section extending above the earth and cement for the portion embedded in the earth.

Another object is to produce a post of this character of extreme simplicity of construction.

Another object is to so construct the post that it will be of maximum strength.

Another object is to make provision for a strong connection between the wood and cement sections.

Another object is to prevent the post from being withdrawn from the earth and also to prevent lateral movement.

Another object is to construct the post in such a manner that the cement sections, as well as the wood sections, can be readly stacked one on top of the other for shipment and storage, so as to occupy a minimum space.

Another object is to make provision whereby drying out of the wood section will not produce looseness between it and the cement section.

The accompanying drawings illustrate the invention:

Figure 1 is a front elevation of a post constructed in accordance with the provisions of this invention;

Fig. 2 is a side elevation of the post shown in Fig. 1 from the right thereof; and

Figs. 3 and 4 are plan sections on lines indicated by w w and a2 m, respectively, Fig. 1. V

The post comprises a wood section or member 1 and a cement section or member 2. The cement section may be provided with the usual metal reinforcement members indicated at 3, 4. The cement section 2 in cross section is channel shaped, the web being indicated at 5 and the flanges at 6. In cross section the section 1 is rectangular and of such dimensions as to loosely fit in'the groove 7 of the cement section. The section 1 is inserted for a short distance in the channel 7 and is secured by bolts 8 which pass duced in depth by fillets 10, so that the section 1 will contact atits inner corners with the bottom of the groove and be spaced from the bottom of the groove nearer its median line. When the bolts 8 are drawn up tight they spring the section 1 at its middle portion toward the bottom of the'groove and, consequently, when the section 1 dries out in the course of time the section 1 will still be under some tension and, therefore, securely held by the bolts.

The rear face of he section 2 is preferably convex, as indicated at 11, so that when a post section 2 is superposed upon another similar section the middle portion of the convex face 11 will rest in the groove 7 and thus tend to prevent the cement. sections from moving out of alinement with one another.

The lower end of the groove 7 is closed by a cross member 12, and the outer face of said cross member is concave, as indicated at 13, so that when cement sections are superposed, as mentioned above, the convex face 11 will fit the concave face 13.

When the fence or other structure is to be built, the post sections 1, 2, will be assembled and the cement sections will be inserted in the holes, prepared for them in the earth, to a plane just beneath the lower end of the section 1, so that after the hole is;

filled with earth the earth will not contact with the wood section. Thus the cement section will protrude for-a short distance When thus above the surface of the earth. placed in the earth, the flanges 6 will tend to prevent ed'gewise movement of the post and the earth resting upon the cross member 12 will effectually prevent withdrawal of the post from the earth.

When the sections 1, 2, are properly aswill not be sufiicie t to enti ely remove the tension in the Wood section" and, .consequently, the bolts 8 Will not become loose and the sections will, therefore, continue to be securely fastened to one another Without any looseness at the joint.

' I claim:

, 1. In a post, a cement member having a longitudinal groove 01": less depth nearer the sides than nearer the middle portion thereof, a second member inserted part Way into the groove and having its inner corners resting upon the bottom of-the groove and having its middle portion spaced from the bottom of the groove, and bolts passing through the middle portion of the secondmember and into the first member.

2. In a post, a cement member having a longitudinal groove, fillets in the corners of the groovefa second member inserted part Way in the groove and having its inner corners seating against the fillets, and means v'to hold th middle portion of the second member toward the bottom of the groove.

3. In a post, a cement member, a second member, bolts connecting the members, and means cooperating with the bolts to produce buckling of the second member when the bolts are drawn up tight.
